Aerzen Rotary Lobe Compressor- The best of both worlds, for high intake volume flows of between 65 cfm to 5,300 cfm. Quiet, Compact, Energy Efficient 

The Rotary Lobe Compressor is the result of a synergy between the rotary lobe blower and the screw compressor technologies.

The Delta Hybrid was developed with the focus on increasing energy efficiency and achieving a significant reduction of energy costs and greenhouse gas emissions.

Wire-to-process energy usage reduction can exceed 30% over typical positive displacement blowers depending on operating conditions and turndown range.

Optimized fluidic design of inlet and discharge ports provides ideal flow conditions and reduced slippage. Additionally, the belt-driven Delta Hybrid offers the significant advantage of matching motor speed and power to the required blower performance eliminating the need to over-speed the blower or oversizing the motor. A 5% excess in volume flow corresponds to a 5% higher energy use.
